  Notes:  
  1.  Water Year (WY) 2010 began on October 1, 2009 and will end on September 30, 2010.  
  2.  Values in shaded areas represent current month.  
  3.  PROD = Production;  ANT = Anticipated; ACT = Actual.  
  4.  Actual WY 2010-to-date production of 12,274 AF includes 1,111 AF produced in the LCV (Dec 2009 - May 2010), and injected into the Seaside Basin.
  5.  Seaside Coastal monthly production target of 575 AF includes 25 AF of anticipated production from the Sand City Desalination Plant.
  6.  Usable reservoir storage volumes are based on capacities as follows:  
            San Clemente Reservoir (CAW, 2003):  137 AF (elev. 525') - 71 AF (min. pool @ elev. 515') = 66 AF  
            Los Padres Reservoir (CSUMB, 2008):  1,731 AF (flashboard out @ elev. 1038.90') - 105 AF (min. pool @ elev. 980') = 1,626 AF.  
                                                                           1,774 AF (flashboard in @ elev. 1039.78') - 105 AF (min. pool @ elev. 980') = 1,669 AF.  
  7.  Flashboard removed from Los Padres Dam notch 10/23/09 and re-installed 8/20/10.  
  8.  LP storage change of 21 AF is a computed value resulting from the change in reservoir capacity due to board installation, not actual water stored.
